  1. Water in Emergencies Session 7 Medium Term Water Responses W7

  2. Medium Term Responses • When immediate needs are met develop medium term responses • More participation / user engagement • Improve water quality – bulk or household treatment • Easier to sustain for medium term • Reduce recurrent costs W7

  3. Spring Water – by Gravity or Pumping Rehabilitate / protect Extend pipelines Protect new Agree with existing users Check with landowner Spring being used to supply a refugee camp in Uvira, Zaire S House / WEDC W7

  4. Rehabilitating, Improving or Constructing New Shallow Wells Ethiopia S House / WEDC Liberia S House / ACF Uganda S House / MSF-OCBA W7

  5. Boreholes – Medium Depth or Deep Groundwater Mechanical Pumping Schemes: Expensive O&M Permission for drilling Potential impacts Ethiopia S House / WEDC W7

  6. Improving Bulk Water Treatment – Coagulation & Flocculation O&M requirements REDR / OXFAM W7

  7. Using Private Sources or Services S House AAH-US Small water sellers – take water from both private and community managed water tanks in Mandera, Northern Kenya Private traditional shallow well, Ethiopia S House / WEDC W7

  8. Exercise – Compare Advantages & Disadvantages for Emergency Contexts • Bottled water • Water from open stream supplied by tanker • Water pumped directly from a lake to tanks which directly feed tapstands • Existing shallow wells disinfected with chlorine • New shallow borehole and handpump • Spring supply fed by gravity pipeline W7
